I just finished to test the new Catalyst 11.1a hotfix (January 26 2011!!!) to verify the gains in OpenGL tessellation claimed by AMD HERE. My friends, this new hotfix (you can download it here) brings some nice improvements in TessMark, especially in Moderate and Normal tessellation levels (moderate: X8, normal: X16, extreme: X32 and insane: X64).

– Graphics card: SAPPHIRE HD 6970
– CPU: Core i7 960 @ 3.2GHz
– RAM: 4GB DDR3 Corsair Dominator
– Motherboard: GIGABYTE X58-A UD5
– Windows 7 64-bit
– PSU: Corsair AX1200

PSU Corsair AX1200

TessMark settings: 1920×1080 fullscreen, no AA, no PostFX, map set 1.

Scores with Cat 11.1a Jan26 and the last WHQL Cat 10.12:

Catalyst 11.1a Hotfix Jan26_2011:

  • Moderate: 31562 points (526 FPS): +14.9%
  • Normal: 9781 points (163 FPS): +18.86%
  • Extreme: 2201 points (37 FPS): +3.7%
  • Insane: 541 points (9 FPS): +0.37%

Catalyst 10.12:

  • Moderate: 27469 points (458 FPS)
  • Normal: 8229 points (137 FPS)
  • Extreme: 2122 points (35 FPS)
  • Insane: 539 points (9 FPS)

More scores are available here: SAPPHIRE Radeon HD 6970 OpenGL performances.

I did the test with a freshly compiled version of TessMark (I will release it this week) because I noticed some crashes with the current TessMark 0.2.2 and Catalyst hotfix.

I also tested the OpenGL tessellation with Unigine Heaven 2.1.

Settings: 1920×1080 fullscreen, OpenGL rendering, tessellation: normal, shaders: high, AA: 4X, 16X anisotropic filtering.

Catalyst 10.12:
– 24.7 FPS, Scores: 622

Catalyst 11.1a hotfix Jan26:
25.9 FPS, Scores: 654: +5%

And here is the DX11 score with the same settings and Cat 11.1a hotfix:
42.0 FPS, Scores: 1057

There is still an important bottleneck somewhere in AMD’s OpenGL driver…

    Have you tried the new tessellation level slider to see how well it works?

  • The tess level slider has no effect, at least on TessMark.

  • Leith Bade

    Well thats typical of AMD. (Announcing new features that are broken)

  • A Keenan

    The tesselation slider does work as ive got it up and running on a lowly 5870 and have it working perfectly in unigine etc, But surely it shouldnt be used in benches as its CHEATING

    Ok just installed on hd 5970 hardware , I ve got the new tessellation slider like other 6xxx radeon , i’m able to say that the slider has strictly no effect in term of fps during the benchmark in dx 11session- Tess and dof enabled obviously …. Same avg fps with slider toggled to x2 or maxed out to x64…

    Ça marche pas visiblement ..,,

    45 fps avg max 133 min 13
    1920×1080 AAA hfx16 dx11 Tess on dof on
    Maxed out without msaa option.
    5970 (960/1260) -q9550 @ 3.93ghz- 4 go pc 8500 cas5
    Win 7 x64 up to date.

    Sry I’ve forgotten one thing : I’m talking about the metro 2033 dx 11 game benchmark.

  • @Komar: avec AMD ça marche rarement du premier coup 😀

    Watchout the whql drivers are not so good in term of performance than the beta leaked drivers 11.1 hotfix a…

    Many people have noticed that fact : final driver is weaker than leaked one … Omg with AMD , you’ll never stop downloading odd exotic stuff…

    By the way Cf works well with my 5970 with hotfix fixing the tessellation issue under tessmark open GL session .

    New tabs , new possibility on 5xxx hardware I can say that beta hotfix rocks solid instead of new whql one….
